Because of its utility, it inspired many and later became one of the roots of the free software movement and open-source software. Numerous operating systems were based upon it including Minix, GNU/Linux, and the Berkeley Software Distribution. Apple's macOS is also based on Unix via NeXTSTEP [ 11] and FreeBSD.
The history of free and open-source software begins at the advent of computer software in the early half of the 20th century. In the 1950s and 1960s, computer operating software and compilers were delivered as a part of hardware purchases without separate fees. At the time, source code —the human-readable form of software—was generally ...

An operating system ( OS) is system software that manages computer hardware and software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and ...
The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. [ 1] Multics introduced many innovations, but also had many problems.
Linux is the leading operating system on servers (over 96.4% of the top one million web servers' operating systems are Linux), [26] leads other big iron systems such as mainframe computers, and is used on all of the world's 500 fastest supercomputers [d] (as of November 2017, having gradually displaced all competitors).

FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version of FreeBSD was released in 1993 developed from 386BSD [3] and the current version runs on IA-32, x86-64, ARM, PowerPC and RISC-V processors.
